Novel Conducting Polymer Structures For Electrochemical Actuators, Binbin Xi
Novel Conducting Polymer Structures For Electrochemical Actuators, Binbin Xi
University of Wollongong Thesis Collection 1954-2016
Electrochemical actuators based on conducting polymers and conducting polymer/carbon nanotube composites have been constructed and characterised. The actuation performance was optimised in terms of the actuation strain, cycle life, stability and work-per-cycle. Different conducting polymers, such as polypyrrole, polythiophene, and polyaniline were investigated as actuator materials. More reproducible and stable strain response from polypyrrole actuators has been achieved by the combination of current pulsing control for electrochemical stimulation and ionic liquid for the electrolyte. Current pulsing ensures that the oxidation and reduction processes are equal in their magnitude and prevents the slow net oxidation (or reduction) that typically occurs during …
Electrochemical And Photovoltaic Properties Of Poly(Thiophene)S, George Tsekouras
Electrochemical And Photovoltaic Properties Of Poly(Thiophene)S, George Tsekouras
University of Wollongong Thesis Collection 1954-2016
The utilisation of conducting polymers for photovoltaic applications represents the possibility of low-cost production of solar electricity. The chemical modification of the precursors used to prepare conducting polymers provides an avenue to the tuning of the photovoltaic, rheological and solubility properties of conducting polymers to suit photovoltaic applications. Poly(thiophene)s have been widely utilised by researchers in the field of conducting polymer photovoltaics. The present study in part considered the utilisation of a range of thiophene precursors, in particular terthiophene derivatives, for the preparation of polymeric photoactive layers within photoelectrochemical cells. These precursors included a C60-substituted terthiophene derivative, 3-alkylthiophenes and ethersubstituted …

Development Of Chiral Conducting Polymers For Asymmetric Electrosynthesis, Yingpit Pornputtkul
University of Wollongong Thesis Collection 1954-2016
This thesis describes novel synthetic routes and characterization of chiral conducting polymers based on aniline and substituted anilines that have potential applications in the areas of asymmetric electrosynthesis and chiral separations. Ionic liquids and novel chiral ionic liquids are used as novel electrolytes for the polymer synthesis and for improvement of the electrochemical stability of chiral polyaniline doped with (+)-10- camphorsulfonic acid. Electroorganic syntheses using bare or chiral polyaniline modified electrodes in ionic liquids or chiral ionic liquid electrolytes are explored. Following an Introduction and a General Experimental Chapter, the new studies are described in Chapters 3 to 10. Chapter …
